Be it known that l. r'ioonrii ERAT, a citizen ot the United States ofAmerica, and resident of Easthanipton, in the county of Hampshire andState of Massachusetts, have invented certain new and useful 1mprovernents in Non-Skid Devices for Automobiles. of which the followingis a full, clear, and exact description.

This invention relates to improvements in means for preventingautomobiles and vehicles from skidding and consists in the provision ofa sand receptacle ada ted to be supported on the running board of anauto mobile or vehicle, under one of the seats or otherwise as may bedesired and means controllable from the dash board of the vehicle forpermitting quantities of the sand to flow onto the ground in advance ofth rear wheels.

Another ob'ect of the invention is to oro vide means for regulating theval e action controlling the outflow oi the sand.

With the above and other objects in view the invention relates tocertain new and use ful constructions, combina ions and arrangenients oiparts, clearly do 'crbed in the tollowin'g specification and fullyillustrated in the accompanying drawings in which:

' 'gure 1 is a side elevation of an autoinobile showing the sandreceptacle mounted on the running board of the vehicle.

Fig. 2 is a vertical longitudinal sectional. view through the coincontainer and valve.

l 3 is a transverse sectional view of an enlarged scale of the valve.

l l is a tront elevation of an operating indicator.

Fig. 5 is a plan view of an automobile showing a modified form of theinvention.

F 6 is a VEl'LlCfll sectional. view thereof on an enlarged scale.

Referring to the accompany"inndrawing ii designates an automobile oi anyapproved construction which is provided with rear wheels B and a runningboard (1. o

On the running board C a receptacle 5 is disposed and provided with asand distributing nozzle or outlet 6 which is downwardly and rearwardlydirected distribute sand in advance or" the rear wheel au 'acentthereto. A similar receptacle being located on the opposite side of thevehicle.

A valve member 1 shown to be in the term of a tilting valve dislr ispivoted upon the shaft 8 in the outlet member 6 to prevent and regulatethe outflow of sand from the receptacle 5 and the valve member or disk 7is operated by means of a wire or cable 9 which is connected to thecrank 10 of the shaft 8.

The wire or cable 9 extends forwardly to the dash board over the guide11 and is connected with the cranlr. arm 12 mounted upon the shaft 13,which is arranged to rotote. on the dash board D. The shaft 13 carries alrnob i l on its outer end which is equipped with a pointer 15 movableover the dial 16, which is provided with a series of numbers or lettersor indicating various adjustments of the disk valve or member. lhe dial16 is also provided with small notches 16 whereby the pointer 15 may belocked in registration with either of the numbers or adjustment pointson the dial.

In Figs. 5 and 6 I show a modified torrn of the invention wherein asingle receptacle 20is employed, which may be mounted on the trains oithe vehicle in any suitable position and which is provided with a pairof diverging distributing pipes 21 and 22 which are adapted todistribute the sand against the rear wheels 23.

The outflow of sand from the receptacle 20 through the distributingpipes 21 and 22 is controlled by means of a single valve 24 pivoted uponthe shaft 25 and operated through tne medium of the lever 26 and theoperating wire or cable 2? which extends forwardly and has operativeconnections with the lever 12 of the dash board equipment. in both formsof the invention the dislr valve is held in a normally closed posi. tionby means or the spring 28.

lVhen the driver passes over a road that is slippery'he can instantlydistribute sand in advance of the wheels so as to prevent skiddingandthe action or" the sand will absolute. y insure a positive non-slippingtraction of the wheels upon the roadway.

Having described any invention 1 claim:

A. non-skid device for automobiles consisting of a sand receptaclehaving a single outlet and diverging; distributing pipes con nectedthereto for distributing; sand in advance of the wheels of theautomobile, a

valve disk located in the outlet for opening and closing the same, alever connected with said valve disk, a shaft adapted to be mounted onthe dash board of the automobile, a crank arm connected With said shaft,a flexible connection between the crank arm and the lever and a dial forindicating on the dash board the position of the valve disk relative tothe outlet. 7
